Application filed November 30, 1915'. SeriaI No. 64,277.

To all whom it may concern:

' Be itknown that I, JOHN K. GREEN, a citizen of the United States, and a. resident of the borough of Manhattan, county, city, and State of New York, have invented certain new and useful Improvements in Anchorldolts, set forth in the following specificatlon.

This invention relates to a new anchor bolt for use with safety devices for window cleaners and to a new method of applying anchor bolts for such purposes.- The object of the invention is to cheapen and facilitate the manner in which an absolutely secure anchorage for safety "window cleaners de vices may be applied to windows during the construction of a building. A further object of the invention is to provide an improved anchor bolt for use in the furtherance of the new method of providing anchorages.

Heretofore it has been customary to in stall anchor bolts in one of three general ways. One way was to embed a webbed an chor bolt between the partings of the brick or stone work surrounding a window opening during the laying of the brick or stone work. A second way was to. drill a hole in the brick work or stone work and secure therein an expansive bolt; a third way was to screw a lag bolt into the woodwork of the window frame. The first way was very expensive, although a satisfactory permanent anchor resulted. The second wa was likewise expensive and had the addltional disadvantage of relying upon an expansion bolt often worked loose. The third way has often proven unsatisfactory because of the splitting of the wood.

The present invention marks a radical ad vance step both in results and method of achievement. An anchor bolt is provided which has a suitably headed bolt shank formed at its outer end projecting out at a suitable angle so that the same will be exposed in the exact direction best adapted for receiving the I strain of safety apparatus when a window is completely framed into a building. This special anchor bolt may with great facility be attached at the proper elevation, one on each side of a window frame, after the completion of the window frame in a shop, but before thesame is built into the wall of a building. Thus, when the window frame is in the shop, attaching means such as screws may be used to attach the anchors at localiposite end 5 ties where substantially the entire framing of the window frame is engaged by the attaching screws. The particular location of the anchor is also such that the brick or stone work about the window frame will be built up to inclose and embrace the anchor, concealing it to give a good finish and at the same time increasing the strength of its anchorage. This building up of the stone or:

brick work may be accomplished without the need of paying any particular attention to a the anchors as is the case when the same must be applied between the partings of the masonry.

The manner in which the object of the in vention is accomplished will be understood from the illustrative embodiments of the invention covered in the accompanying claims, described below and illustrated in the accom panying drawings, which form apart hereof, in which like characters designate corresponding parts, and in which perspective view of the pre- Figure 1 is a ferred form of the anchor bolt;

In Fig. 1 there is illustrated a fiat elongated webbed portion A which is provided with two lateral projections 1 and 2 near the outer end 3 and with a toe 4 at the o occupying a position at rig t angles to the plane of the webbed portion A. The bolt shank B provided with a bolthead 6 of any desired configuration is preferably cast or forged integral with the webbed portion A and is merged into the same so as to extend outwardly therefrom at an obtuse angle as shown best in Fig. 2, but should be reinforced at its base in a suitable manner as by buttresses 7, 8 and 9 and webs 10 and 11. Screw holes 12 and 13 are provided in the projections 1 and 2 and also a screw hole 14 in the toe 4. This entire anchorage structure may be termed the anchor bolt, is designated C and may preferably be made of bronze. The projections 1 and 2 and their screw holes 12 and 13 are located so that screws 15 and 16 driven therethrough will pass through the frame-piece 17, through into the stile 18 so that a strong firm anchor age results. The extent of the web portion A is preferably such that the toe 4 grips about the inner edge of the frame-piece 17 and may be secured thereto by suitable means such as the screws shown in dotted lines. The window frame D is fitted with a suitable number of the anchors C suitably positioned. This is done at the factory. When a window frame D is applied to a building and built in by the laying of the masonry E the anchor C is likewise built into the masonry without purposeful effort. In fact an anchor C cannot be removed with out practically demolishing the entire window frame and building wall.

When an anchor of the invention has been applied in the manner described and the masonry E has been built up, it is customary to apply to the window frame a staff bead 30. Advantage may be taken of this staff bead to conceal all except the desired amount of shank B and the bolt head 6. All that is necessary is for a carpenter to cut away a suitable socket 31 .in the bead 30 to accommodate the parts of the anchor C to be covered asshown in Figs. 2 and 4.

To make possible the advantages of this invention, it is contemplated that it is not necessary that the anchor C ,comprise the exact configuration shown in Figs. 1, 2 and 3. For example in Fig. 5 .a modification C is shown in which the lateral projections 1 and 2 merge into the elongated part of the web ortion A along curved lines 20 and 21 whic may ive added strength to the structure. Anot er modification is the termination of the elongated web portion at the 10- cality 22 and the provision of a suitable attaching means, such as the screw 23 adapted to pass through the frame-piece 17 into the rear'frame-piece 24 of the window frame D.

In Fig. 6 in the modification C the elongated web portion A comprises two legs 25 and 26 making a triangular shaped structure with the front web 27 In this structure the toe 4 is present, although it is contemplated thatthis triangular construction may be adapted in the manner shown in Fig. 5 with the elimination of the toe 4.

In Fig. .7 in the modification C an L- shaped web portion A is illustrated, the lower lateral projection 1 being omitted.

In Fig. 8 in the modification C the struc ture is similar to that of Fig. 5, except that one stron screw 30 located near the root of the bolt s ank B is substituted for the two screws 15 and 16. Nevertheless the lateral projections 1 and 2 strengthen the shank against a tendency to turn.

In Fig. 9 the structure C is similar to that of Fig. 6, except that the web portion A assumes a substantlally elliptical formation, the toe 4 being illustrated. It is to be understood, of course, that the toe 4 may be eliminated in this modification also by providing means for attaching the same through to the rear frame 24.

What is claimed and what is desired to be secured by United States Letters Patent 1. An article of manufacture comprising a window frame adapted to be built into masonry building construction having a pair of safety-window-cleaning-device-anchorages fixed thereto at predeterminable locations, each said anchorage having a thin web portion secured to the outer wall of said window frame and a bolt head fixed to said Web-portion and extending out from said window frame at a locality not adapted to be covered with masonry.

2. In an anchor bolt for safety window cleaning devices, a Hat elongated web portion having a lateral projection near its outer end and adapted to besecured flat against the outer face of a window frame; and a headed bolt shank formed at the outer end of said web ortion and extending out therefrom at an obtuse angle to the plane of said web portion.

3. An anchorage for safety window cleaning devices comprisin a web portion having one or more rearwar ly extending members and at the front one or more members extending generally transversely to said rearwardly extending member, said members having erforations to accommodatescrews; and a s ank having a bolt head extending out obliquely from said one or more laterally extending members of said web portion.

In witness whereof, I have signed my name to this specificatiomin the presence of two subscribing witnesses.
